🔥 Natural Gas Power Plants in Arizona
Arizona operates 34 natural gas power plants totaling 18,578 MW of nameplate capacity. Annual generation: 51.3M MWh.
Natural gas plants are the workhorse of the modern grid. Combined-cycle units achieve very high efficiency and can ramp up and down quickly to balance variable renewables. They emit roughly half the CO₂ per MWh of coal and far less of other pollutants, but they still release upstream methane during fuel extraction.
